# CoachAI

> CoachAI is a simple idea executed thoughtfully: point your iPhone at yourself while you work out, and it uses the camera to watch your form and count your reps in real time. The catch that usually kills fitness apps like this, privacy, is handled by doing all the processing on-device, so no video of you sweating in your living room ever gets uploaded anywhere. It also tries to be a little smart about coaching, adjusting its workout recommendations based on how clean your form actually looks rather than just logging what you claim you did. It launched in 2026, landed at number 16 on Product Hunt on its debut day, and the makers cheerfully shipped it unfinished to gather feedback from real users. For a non-engineer, the appeal is that it turns the phone you already own into a form check without a trainer or a subscription to a camera in your gym. It is a nice example of on-device AI doing something genuinely useful and staying out of the cloud while it does it.
